You need to use each MzScheme.exe executable with its own PLT tree.

I think that a full path specification in Emacs is the only sane
option on Windows. If you don't do that, then it's probably better to
add "c:\program files\plt" into your path -- either before "c:\bin",
or just get rid of the 371 installation (and the respective
executable) there.

If you run into installation problems, it should be safe to just
remove all PLT directories and executables, and then reinstall it.
The new installation will overwrite the registry entries and start
menu.
